Can't say much about three lakes but have a little information on Bull Creek. For what it's worth:

Hunted it last year for a change and to see what eles was available. Talked to the older gentelman at the check station and he told me about the west side about a mile to two miles in. Cut straight west to the fence line, (private property), and head south. Did just as he said and found an area that just hit the spot for me. Next morning heard turkeys all over the place but none close enough to shoot. Only got to go that one day but it was enough to want me to go back. Saw turkeys walking across the road and in the feild behind the fence, (private property). Really got my blood pumping. As far south as I live one just dosen't see that many Osceolas walking right out in front of everybody.

This was late in the season for me, just trying to extend my season before heading up north. If you can, try to get there at the opener, way more turkeys to be had.

Green swamp is set up kinda the same way and I would recomened it to you also. Check stations at the entrances, with a oval type dirt road with in. You can park your truck and then walk either left or right of the road to your spot.

Alot dryer than I'm used to, and the gators, IMHO, are not a problem.

If you need some more information just ask I'll do my best. Really liked these to spots and plan on going again this year.

Your alowed to camp outside the entrance at both places. That's what I do, to keep the cost down.

Hope it helps.
